Interstellar Travel on the Starship Hack Circus

About a month ago, I blasted off on the Starship Hack Circus. About fifty other people and I headed towards KOI-3284.01, and I was never to see my friends or family or Earth again. Theoretically.

Hack Circus is an English magazine and podcast about science and technology, and their Starship event coincided with the launch of their newest issue, “First Contact.” The issue is full of interesting and innovative articles — uncontacted tribes on Earth as analogous to intelligent extraterrestrials, how to knit the Arecibo message, and other cosmic quirks. Their launch event was no exception.

For three hours, I participated in an excellent example of creative science communication. Starship Hack Circus presented four experts giving short talks on space exploration and planetary science, but these were far from your traditional lectures — they formed an immersive and interactive experience.

The event wasn’t just “themed”; it took a step further, making you feel like you were on a spaceship bound for an exoplanet. By combining artistic radio technology, speculative SETI, and recordings of stellar and planetary vibrations, the talks were simultaneously informative and attention-grabbing. Audience members weren’t just spectators — we were active participants. We were encouraged to live-tweet during the event using the hashtag #StarshipHackCircus, recording our responses to science in real-time.

In addition to futuristic interplanetary travel, Starship Hack Circus also boldly indicated at another way of the future — science communication’s future.

Starship Hack Circus was an example of the kind of cross-medium sci comm that has the potential to reach millions of people and carry us into the future of learning.  Digital media — blogs, Twitter, Massive Open Online Courses (MOOCs) — are now supplementing and complementing traditional physical media like lectures, textbooks, and papers. Live-tweeting at conferences has become increasingly popular in the last few years, allowing people to keep up with science news from anywhere in the world. We’ve come a long way from monologuing lecturers. Modern science communication is creating a well-rounded database of knowledge that’s accessible to an ever-increasing portion of humanity.

And it’s straight up exciting.

Mechanical Mars – An Interactive Post

When I first saw the Mars chamber I would be working with, I felt just the tiniest sense of utter bewilderment, and possibly a hint of panic. I am not an engineer, and this thing looks mega intimidating.

Thanks to the awesome Rita Kajtar, who made major contributions to the chamber’s construction as part of her masters thesis, I began to understand its various bits and pieces. But still, I knew I’d have a hard time explaining it to you without some visuals. And so, since hands-on learning is the best learning, I made you an interactive photo! Mouseover for some enlightenment.

And here’s the sample tray that goes inside of the Chamber. 

Since science and technology are ever-updating fields, there are of course a few improvements that still need to be made. For example, even though experiments are run under a near-perfect vacuum and condensation is unlikely, a humidity sensor needs to be added. And even though we can use the ideal gas law to make a rough estimate of the temperature during the experiments, it would also be helpful to have a temperature sensor.

The Rocky Road of Experimental Planetary Science

Carl Sagan once said that if you wish to build a Mars chamber from scratch, you must first invent the universe. Ok, maybe he was talking about apple pies, but same thing. [1]

And inventing the universe is what it seems like we’ve been doing the last few weeks. “Simulating the Martian atmosphere” is a much more complex process than just throwing some CO2 into a near-vacuum.

Our “to-do” list is constantly being added to. The UV light needs to be ordered. A cooling system needs to be developed so the light doesn’t overheat. The seal for the chamber needs to be completely airtight to maintain a vacuum, so that condensation doesn’t occur on the cooling system. Wires need to be acquired and soldered in the proper order to provide power to the cooling system. The workshop guys need to be back from vacation to solder the wires.

Most of our work has been on the parts in the box below. It’s the removable sample holder, rigged up with the UV light and Peltier cooling elements to prevent overheating. Since this is where we’ll be putting the magnetite, it’s one of the most precise and crucial parts to get right.


On the experimental side of planetary science, there’s a lot that can go wrong. Patching up our beloved chamber has taken much improvisation and recycling of parts, and there are times when it feels like we’re just putting band-aids on top of band-aids. But much of the beauty in science comes from the attention to minute details to ensure that our experiment is as close of an approximation to Mars as possible. The process of rigor might be riddled with wrenches and soldering guns, but the end result is actually quite elegant.

I’m looking forward to finally starting our first experiment tomorrow.


Science is Coming

8996 kilometers across a continent and ocean. 18 hours of sunshine per day. 10 weeks. One Mars simulation chamber.

Yep, I’m back in Copenhagen. I’m working on a project with the Mars group at the Niels Bohr Institute, using a Mars simulation chamber to examine the big question: Why is the red planet red? Or, more accurately, how is the red planet red? I’ll be determining whether UV radiation can induce the oxidation of magnetite to hematite, the mineral responsible for Mars’ distinctive shade. I’m very thankful to be funded by the Monticello Foundation at Caltech.

This is my nifty version of Mars in a box.

Because I’m passionate about reaching a broad audience with my scientific endeavours, I’m starting this blog to document my science shenanigans, from mineralogy in the Mars chamber to my caffeinated attempts at learning Python. Science should be for everyone, so every week I’ll be updating you, and your grandma, and your dog, about what I’m currently working on.

But I’m no world-class researcher (yet). I just finished my third year of undergrad at Caltech, double-majoring in Planetary Science and Philosophy (you might think this is an odd combo — I’ll blog about it soon). I like philosophizing about alien life, experimenting with different genres of journalism, and hunting for the best cappuccinos in Denmark. As an exchange student in Copenhagen last fall, I fell in love with the city and decided to come back for this summer project.

As I’m trying my hand at this science communication thing, there will probably be some typos and inaccuracies throughout — remember, this is my journey through the dark forests of literature searches and experimental trial and error. Science communication is a two-way street, so interaction with you all is important — if you read something that makes no sense or is just plain wrong, write me a comment!

Brace yourselves — science is coming.
